... and wavelet domain methods, respectively. Note that in the frequency domain method, FFT is used to transform the time domain signals into the frequency domain, while discrete wavelet transform is used in the wavelet domain method. Step 5. Compare the analytical and the reconstructed unknown-set response...

...K. Krishnan Nair; Anne S. Kiremidjian In this paper, a damage sensitive feature based on the wavelet transform of the vibration signal is derived. The theoretical aspects of wavelet decomposition of vibration signals are presented. It is shown that the energies of the wavelet coefficients...

... propagation wavelet transforms Wave propagation deals with loading of high-frequency content and FE formulation for such problems is computationally prohibitive because it requires large system size to capture all the higher modes. These problems are usually solved in the transformed frequency domain...

...S. S. Law; X. Y. Li This paper discusses the extraction of the wavelet-based impulse response function from the acceleration response using the discrete wavelet transform (DWT). The analytical formulation of the sensitivity of the DWT coefficient of the impulse response function with respect...

...L. Zhang; S. T. Quek; Q. Wang, Mem. ASME The applicability of Gabor wavelet transform of time history data in detecting a thin damage in beam is examined. For the case where the damage position is completely unknown, the use of two load positions is suggested. Cases considered are the position...
